LUBRICATOR FOR WINDM ILLS.-

SPECIFICATION forming part of Letters Patent No. 652,785,dated Ju1y 3,1900. Application filed October 14, 1899- Serial No. 733 ,621. (N 0model.) 7

To all whom it may concern:

Be it known that I, HORACE M.KEITH,a citizen of the United States,residing at Commerce, in the county of Oakland and State of Michigan,have invented certain new and usefullmprovements in Lubricators forWindmills, of which the following is a specification.

Towers of windmills are constructed'for climbing as a means for reachingthe bear ings of the working parts to oil them, and my improvements aredirected to novel means whereby this may be effected from the ground bya single rope controlling means for lubri eating all the bearings, andthe particular matters of my improvement will be pointed.

out in the claims concluding this specification, in connection with theaccompanying drawings, in Which a Figure 1 is a side elevation ofthereto. Fig. 2 is a vertical section of an'oiltank surm ounting thetower, having conduct ing-tubes and a Vertically-slidable and rock- Iable bar of cups or cells in the position it 00- cupies within the tankto empty the cups.

' showing the cup-bar in the position it occupies in being raised todeliver the oil into the conducting-tubes through the tank-openings, andFig. 7 shows the oil-tube connection with the crank-pin. v

In the'drawings I have shown so much of the head of a windmill asrevolves about and upon the wear-plate of the tower; but my oilingdevice can be applied to any windmill.

The pump-rod 1 is connected by a pitmanrod 2 to the crank-shaft 3 of thew ndmill, and the bearings of these parts are sufficient to illustratethe application of my cup-bar oilfeeder.

An oil-tank 4; is supported and braced upon the head above the bearingsof the working parts. and may be of any suitable construction,preferably of rectangular form. On one of its outer Vertical sides thetank has a numthe tower of a windmill having my improved oiler appliedFig. 6.

It may hold one or more gallons of oil tubes is a horizontal bar 8,containing cups and arranged to slide vertically in guideways 9 and tobe rocked on ,the inner wall of the tank. This bar is preferably ofwood, be-

cause of. its cheapness and lightness-and of square cross-section, sothat it has a flat side slidable upon the wall of the tank. .At its ends10 itis rounded at one corner, Fig. 4, of

the square, which maybecalled the rear lower angle, so as to permititto'be rocked a quarter of a circle in itsguideways. The

cups or cells are formed by transverse bores 11, preferably obliquely tothe square, and

have short spouts 12, so that when the bar is depressed and immersed inthe oil'the spouts stand up and the cells or cups are filled, as in Theinclination at which the spouts are set will cause their ends to restagainst the tank-wall to prevent the bar from rock ing, so that the barmust rise with the spouts so standing to retain theloil. c. When,however, the feed-bar is caused to slide up in its guideways to bringthe scoop-shaped endsof the spouts in the tankwall openings 6, itjiscaused to rock or turn toward the wall, and thereby project the spoutsthrough the said wall-openings, so as to pour the contents of the cupsor cells into the conducting-tubes.

It is to allow the cup-bar to so rock that its ends 'are rounded; butthe function of these rounded ends is only rendered possible when thespout ends are moved into the wallopenings and the force to raise thebar is exerted at a point thereon to cause it'to rock. This rockingmovement is prevented as the cup-bar is being pulled up, and thecup-spouts arecaused to'retain their upright position by reason of theflat side of the bar and the ends of the spouts being held in contactwith the inner wall of the tank. Referring, toliig.- 3, it is seen howthe cup-bar retainsit's upright position on its Way up by the liftingaction of the rope, as seenin Fig. 6, which constantly tends to causethe bar to turn toward the wall to cause its spouts to dip outward. Asthe spouts on their way up reach their respective openings their endshave no support to resist the turning of the bar and itis caused torock, and the spouts are thereby turned down into the openings, as seenin Fig. 2. In Figs. 3 andt both ends of the cup-bar are shown as roundedto allow it to rock while being held in position by the guideways. Inthe construct-ion shown the normal position of the cupbar is at itshighest when delivering the oil, and it is operated by a vertical rod13, jointed to and rising mediately of the bar and passing through anopening in the top of the tank,

and which rod is connected to a rod-spring 14, secured to and risingfrom the tank, so as to constantly pull the cup-bar upward. To fill thecups or cells, a cord or chain 15, connected to the upper end of the rodor spring and extending to the ground, is pulled, which pulls or forcesdown the cup-bar to immerse its cups, and releasing the pull of the ropethe cupbar is automatically lifted and automatically rocked orturned toplace its spouts into and through the wall-openings to pour out the oil.It is the lifting function of the spring, the provision ofwall-openings, and the capacity of the cup-bar to rock that give theautomatic delivery of the oil from the tank to the bearings, and forthis purpose the spring may be of any suitable kind and arrangement. Anyother lifting means may be employed, and the normal position of thecup-bar may be at the limit of its descent, as it is evident that inthese particulars my invention is not limited to the construction shown.

It is important to note that the cup-spouts when projecting into thewall-openings i11- cline downward and so are held by the action of thespring and are rocked back to the position in which they are caused toslide down against the tank-walls when the ground-rope is pulled. Thetank-wall openings are arranged in horizontal line and the pouringthatwhen the spouts enter said wall-openings they are held in pouringpositions. It is important also to note that the lifting-rod is hingedor jointed to that side of the cup-bar at 15, Fig. 6, opposite to itswall-bearing side, so that it is the lifting action of the rod thatcauses the bar to be rocked or turned to project its spouts into thewall-openings and the pulling down of the rod that causes the bar to berocked back to withdraw its spouts from the openings. The jointing ofthe rod to the cup-bar at that side away from the spouts gives aneccentric action upon the bar to cause it to turn, while the rounding ofone of the angles of the bar at its ends allows it to turn only aquarter of a circle back and forth.

In Fig. 7 is seen a funnel on the crank-connecting pitman-rod to receivethe oil from the conducting-tube 5 during the vibration of the said rod.
